DIFFUSION REVIEW WORKSHEET 1. Define diffusion and what causes it to occur? The action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic:

Précis: In "The Human Cost of an Illiterate Society"‚ Jonathan Kozol‚ a Harvard graduate‚ argues that illiteracy cause the loss of choice or freedom and leads to many problems. Kozol highlights his argument with examples of when illiteracy can be binding such as "Many illiterates cannot read the admonition on a pack of cigarettes. Neither the Surgeon General’s warning nor its reproduction on the package can alert them to the risks."(20). He gives extensive and detailed scenarios in order to raise

differences. We used PhysioEx software to examine diffusion. In these experiments we used different sized membranes as well as NaCl‚ urea‚ glucose‚ albumin‚ powdered charcoal‚ and KCl. The step by step process was used by the software so that we could see the different kinds of reactions. According to the data found‚ we found that with high molecular weight compounds are too large to penetrate the molecular weight cut off pores and no simple diffusion can occur. So it seemed like the easiest way for

The Human Cost of an Illiterate Society By Jonathan Kozol Main Idea: The negative affects illiterate people have on themselves‚ their family and society. Supporting Details: Illiterate people often do not understand the bills they receive and are not able to write the checks to pay them. They often are in the situation of signing documents that they do not understand (230). Illiterate citizens very seldom vote. They are not able make informed decisions based on serious printed information

English 1301 October 31‚ 2011 The Human Cost of an Illiterate Society In Jonathon Kozol’s eye opening essay‚ he discusses in depth the negative effects that illiteracy has on everyone in the American society. Unfortunately illiteracy is a common problem today and is usually more prone in lower income families and is passed down through the generations. When your parents can not read or write‚ you grow up without the importance of being taught these skills and then the cycle of illiteracy

The Human Cost of an Illiterate Society The Human Cost of an Illiterate Society by Jonathan Kozol‚ is an article which illustrates the reality for millions of Americans‚ and the impact illiteracy has on the overall population and that individual and their family. Kozol draws emotional and personal stories which impact the reader as well as allude that the lack of literacy is in direct correlation with Democracy and how illiterate people will vote‚ if they even do at all.

The changes in the diffusion of Buddhism and Hinduism through 600 CE greatly impacted these religions such as the popularity of the religions in India and where the religions was being diffused; however‚ a few continuities existed such as they both originated in India. Since Hinduism reinforces the caste system and Buddhism believe in equal treatment of all people which opposes the caste system‚ Buddhism started to spread into other areas other than India to offer an alternative to Hinduism for

1 Diffusion is the movement of molecules (or ions) from a high concentration to low concentration. Diffusion is form of passive transport as energy does not need to be generated. Diffusion is complete when the concentration of molecules is equal on either side of the membrane. Diffusion rate can be influenced by many factors such as: Concentration gradient across the the membrane. Permeability of the membrane to the diffusing substance. Temperature. Surface area of the membrane. Question 2 2.1

Experiment 1 Background Diffusion is a process‚ in relation to the spontaneous movement of molecules from an area of high concentration‚ to an area of low concentration down a concentration gradient. It is a type of passive transport method‚ that requires no cellular energy (ATP). This movement occurs‚ until a state of equilibrium has been established on both sides of the membrane. The diffusion of molecules happens at cellular level‚ through a cell membrane via the pores. The cell membrane

he mass and length of the potato piece must be kept the same in each experiment primarily because they affect the surface area of the piece‚ and varying surface area could have a great effect on the rate of osmosis. This is because in an experiment where the potato chip has a large surface area‚ there is a larger area of partially permeable membrane and therefore more opportunity for water particles to pass through. I will keep the surface area the same by keeping the mass and length
